4. MODE SELECTION
( pH/CD/DO selection )
1)Turn on the meter by pressing the " Power Button "
( 3-2, Fig. 1 ) momentarily.
*
Pressing the " Power Button " ( 3-2, Fig. 1 )
continuously and > 2 seconds again will turn off the
meter.
2)The meter can select 3 kind Mode as :
a. pH, mV ( ORP ) measurement
b. Dissolved Oxygen measurement
c. Conductivity, TDS measurement
Pressing the " Mode Button " ( 3-5, Fig. 1 ) once, the
Display will show the following text in sequence :
PH pH, mV ( ORP ) measurement
do Dissolved Oxygen measurement
Cd Conductivity, TDS measurement
Until the Display show the desired mode the meter will
execute this Mode with default.

5. pH/mV MEASURING and
CALIBRATION PROCEDURE
The meter default function are following :
*The display unit is set to pH.
*The temperature unit is set to .℃
*Manual ATC ( without connect the ATC probe )
*Auto power off.
*The sampling time of data logger function is
2 seconds.
Fig. 2
If the meter is first time to connect
the pH electrode, it should make the
calibration before operation, the
calibration procedures refer chapter
5-4, page 14.

5-1 pH measurement ( manual Temp compensation )
1)Prepare the pH Electrode ( optional ), install the
" Probe Plug " ( 4-1, Fig. 2 ) into the " pH Socket/BNC
Socket " ( 3-11, Fig. 1 ).
2)Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Select the measurement mode to " pH, mV ( ORP )
measurement ". refer chapter 4, page 11.
The Display will show " pH " and " Temp. " indicator.
3)Adjust the manual Temp. value same as the
solution's temperature exactly, the procedures
refer chapter 9-7, page 38.
4)Hold the " Electrode Handle " ( 4-2, Fig. 2 ) by hand
and let the " Sensing head " ( 4-3, Fig. 2 ) immersed
wholly into the measured solution and little shake the
probe.
5)The up main display will show the pH value, the left
bottom display will show the setting manual Temp.
value.
5-2 pH measurement ( ATC , automatic Temperature )
1)All the procedures are same as
5-1 pH measurement ( manual ATC )
but should prepare one temperature probe ( optional,
TP-07 ), insert the TP-07's plug into the " Temp. Socket "
( 3-14, Fig. 1 ), immerse the sensing head of temperature
probe ( TP-07 ) into the measurement solution.
2)The up main display will show the pH value, the left
bottom display will show the sensing Temp. value of
the measured solution.
When not use the Electrode, it should immerse
the " Electrode sensing head " ( 4-3, Fig. 2 ) into
the " Protection bottle " ( 4-4, Fig. 2 )
